Reply With QuoteHuh? Why would that happen? Remove the spare and the ABS quits? No way.
If you pull the handbrake, the rears will skid. The ABS system only effects the hydraulic system, not the cable system with handbrake.

In our cars, is ABS disabled when you remove the tire spare or pull handbrake?

I've read that on some cars theres a system that once you remove the spare, there is a sensor which tells the abs to stop working. So that the brakes work more efficently. And regarding the handbrake issue, I know that on some Integras you can disable abs by putting the handbrake up one notch.

my take on this
is that the ABS is disabled because if a space saver spare is in use it gives erronous readings

Who said anything about BMW producing Integras?
It would make sense to disable ABS when running on spares. However, I was hoping for a way to disable ABS without pulling fuses/modules. There is a purpose for me in doing this.

in an E34 the spare has absolutely no electronic contacts...its just screwed in
pull the fuse
In most cases when you go up one click on cars and trucks, it turns off the day time running lights.
